Main Pillar Cylinders
The main pillar cylinders serve to stow the roof package in the
luggage compartment and to lift it out of the luggage compartment.
When the rear pillar cylinders are retracted, the roof package is
lifted. The roof package is stowed by extending the main pillar
cylinders. A Hall sensor is installed on the right main pillar cylinder
that signals the "Roof panels extended" position to the CTM.
The uniform movement of the roof package is supported by 2 gas
pressure dampers in the main mount.
Rear Module Cylinders
The rear module is opened and closed by the rear module
cylinders. When the rear pillar cylinders are retracted, the rear
module is closed. The rear module is opened by extending the
pistons in the rear module cylinders.
Two Hall sensors are installed on the right rear module cylinder.
The upper Hall sensor detects the position of the opened rear
module. The lower Hall sensor signals to the CTM that the rear
module is almost closed.
Beginning at this position, the pressure in the rear module cylinders
is reduced and the rear module is closed more slowly until it
reaches the end position.
